I made my own mechanical wastgate several months ago but was never happy with the bracket. My fabrications skills and tools are a little lacking so I wasn't able to make anyting suitable. I had thought about sacrificing my wastegate actuator for the bracket but didn't want to do that in case I ever had to revert back to the stock set up.

Well if luck didn't have it screaminxl posted the other day that he was giving away a vacuum pump and a wastegate actuator from a GM-4....Damn I said, if it was for a GM-8 I'd take it. screaminxl responded by saying he also had one from a GM-8 and it could be mine for the meer price of shipping.

Knowing I had a replacement on the way I went ahead and sacrificed mine to the homemade wastegate gods. I cut around the bottom edge of the canister with my sawzall and then used a pair of bolt cutters to cut the actuator rod. I don't know if you can find a better bracket for a homemade mech wastgate controller.

Pics attached.

Thanks again screamin!

Looks great.

Great pics Dave. Thanks for posting them for us. :)

Guess I don't have to make you that custom wastegate now. :cool2:

thats cool I did the same thing. But I sure can't get fullthread to bend that nicely, it always breaks on me.

Thats almost exactly what i did..for a bracket anyways. I used the original rod and clip after i cut the diaphram off. I cut the head off a 3/8 bolt, drilled a hole in the center, put the rod in and welded it there. I had to make the hole in the bracket a little bigger for the bolt but it works awesome.

I would still be interested in that if you're still game for making it. This was just a band-aid solution. No problem if you don't have the time.

Ya gotta heat it up. Clamp the rod in a vice with at least an inch down in the jaws. Put your torch on the front part of the rod right where it meets the vice. Get it nice and hot and it will bend no problem. You'll feel it if you keep pulling forward on the rod as you're heating it. When it gets hot enough it will bend nice and easy. Stick it under water right away after it's bent.

I did the exact same thing just friday, except I cut mine right where they join together, it looks really good..... well its less of an eye sore when you pop the hood....

I was going to do that but I wanted a little more of a platform for the spring to sit on.

Cold Rolled Rod bends great in a vice and makes a nice 90 degree bend.

You just have to thread the end for the nuts to go on.

Can that spring actualy close? it looks almost as tight as it can go.

Here are some pictures of a mechanical wastegate I made.

I used 3" angle iron and 5/16 cold rolled rod.

I used the factory wastegate and rough traced it onto the angle iron and cut it out with a angle grinder.

I drilled a 3/8 hole in the top for the rod to go through.

The 5/16 rod can be bent to a nice tight 90 degree angle in a good vice using a hammer to pound with right close to where the bend is to be made. Leave about 1-1/4 inches to go through the linkage arm and cut to length after.

I bought 12 inches and only used 6 inches. I then threaded about 2 inches where the spring goes.

Close to the bend in the rod, I drilled a hole and put in a cottor pin, then a waher and then the wastegate linkage arm, then another washer and a hitch pin, which can be removed easily.

The rod will not come out of the wastegate arm even without the pins and washers, but it keeps it lined up straight.

You mean open, remember the WG is supposed to be closed and opens with less vac or less spring tension to regulate boost

Good Idea Dave12.

I made extra custom WG brackets when I made mine.
I will have them in the marketplace ASAP.
I have extra springs and rods too.

That looks awesome! Great job.

Why wouldn't you just by a system from Heath Diesel, the master turbo control or whatever they call it. Seems like a lot of work for something that is already on the market. Just a thought.

$$$ may be an issue??

Another reason is alot of us guys like to "tinker" and do the work ourselves.
Just my .05

By making it yourself you get to fully appreciate how much time and effort goes into building and developing a working system. Besides when you open the hood you can accurately describe how the ugly monstrosity works or is supposed to work. :)

Peabody just summed it up. I liked erector sets when I was a kid for tinkering, I prefer things that are proven. However looks are still important to my ugly old 6.5

For me the proof is all us guys that love to build these things and post the results,good or bad. Looks are how much time you spend on your project. Quick and dirty, or thought out and(much) more time for the finishing touches.
